Novel compounds of the formula: ##EQU1## and their use as miticides and mite ovicides, wherein: R.sub.1 is hydrogen, methyl or ethyl; R.sub.2 is methyl, ethyl, methoxy, phenyl, dimethylamino or 2-(dimethylamino)ethyl; R.sub.1 and R.sub.2 can be taken together to form ##EQU2## --(CH.sub.2).sub.n --, or --CH.sub.2 CH(CH.sub.3)--O--CH(CH.sub.3)CH.sub.2 -- where n is 4 or 5, provided that, when R.sub.1 is hydrogen, R.sub.2 must be dimethylamino or 2-(dimethylamino)ethyl.

3,5-Disubstituted 3H-1,2,4-dithiazoles were prepared by the oxidation of dithiobiurets, S-benzylisodithiobiurets, and alkyl trithioallophanates, and then 3-acyl or carbamoylimino derivatives were obtained by the direct acylation or carbamoylation of the dithiazole salts. From the spectral data of these compounds, it is concluded that the carbonyl group affects the pseudoaromatic character of the dithiazole
